A lot of the attention that an exhaust system gets is from the sound it makes going around the track. A particular ATV might be enormously fast but it may not make you turn your head as its going by because it does not sound like it is going fast. A SuperTrapp exhaust system has that impressive sound. Whats nice about a SuperTrapp is that you have the option to tune for decreased volume if your particular riding area requires it. Its a great muffling spark arrestor device. Tom Carlson, Engine Builder, TC Racing
